Here's my problem, 99 Subaru Legacy 2.5 dohc. I had a really bad oil leak at the cam seal (RI)and around the valve cover (right head) and a plug wire that was pulled apart at the boot. Car ran fine no CEL, no ODB2 codes, just a qt of oil every 3 days. I change out the seal, valve cover gaskets, valve bolt grommets, oil & filter, and plug wires (just for g.p. cause if the torn one). Mind you again car ran fine before service. After servicing it also ran fine until it warmed up and drove for 10 or so mins, then began to cut out in 3rd gear @ around 3000 rpm, shift into 4th fine until again @ 3000rpm same in 5th. Had it scanned and camshaft position sensor along with P0301,P0302 & P0304. Cleared the codes, replaced cam sensor and ran fine until engine warmed up and same problems began to arise. T
